To @ZZ whom 111) may concern:

, felly to the desired diameter.-

The invention consists of certain parts and details and combinations ofthe same, as will be hereinafter described and then pointed out in theclaims. I

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Fig. 7 is a perspective view of a felly and Fig.Sis aperspective View of part of the upperswinging bed.

The improved planer is provided with a suitably-constructed frame A, inwhich is journaled the longitudinally-extending cutter head shaft B,connected with suitable machinery for imparting a rotary motion to theshaft, the latter carrying two cutter heads C and C for planing theouter and inner faces of the felly D. The latter is placed rst on thesegmental holder E of a lower felly-supporting bedEhung on a shaftFjournaled in bearings G held adjustably on slides H fitted to slidevertically in suitable bearings in the main frame A. The felly D whenarranged on this lower felly-supporting bed E is acted on by the cutterhead C located directly above the felly and the bed E, so as to planethe outer face of the felly. The latter is next placed on an upperfelly-supporting bed I provided with a segmental holder I on which reststhe felly, the said bed being hung on a shaft F journaled in bearings Gheld -adjustably on the slides H, as plainly shown in Figs. l and 2. Thebearings G and G are secured in place inthe slides H by bolts or pinspassing through apertures in the slides as plainly shown in Fig. 1, sothat the bearings can be raised or lowered for larger or smaller beds Eand I used according to the radius of the fellies to be treated. Theupper bearings Gl have their apertures for the bolts elongated as shownin Fig. l, to permit slight sliding movement in a vertical direction ofthe said bearings, the shaft F and upper bed I', for the purposehereinafter more fully described. The felly D is then in alignment withthe other cutter head O', so that the latter is adapted to plane theinner face of the felly, as hereinafter more fully described.

` In order to hold the felly D on the segmental holder E', I provide therear end of the same with a stop F.2 provided with pins adapted toengage one end of the felly, as plainly shown in Fig. 2. On the sides ofthe holder E are arranged short lugs E3 extending upwardly to engage thesides of the felly to prevent the same `from shifting sidewise, it beingunderstood that the oppositely arranged lugs are arranged a distanceapart corresponding to the thickness of the felly; see detail Fig. 5. Onthe other segmental holder I and near the Vforward end of the same isarranged a stop l2 similar to the stop E2 and serving to engage the-forward end of the felly for holding the same in place. p The rearwardend of the felly when resting on the holder I is adapted to be engagedby a lever I under the control of the operator and pivoted on the bed I,as plainly shown in Figs. 2 and 3. A spring I4 presses on the said leverIB to hold the latter in its normal positionas shown in Fig. 2, that is,against one of the side arms'of the bed I. When the operator takes holdof this lever I3 and presses it forward to the position shown in Fig. 2,in dotted lines, and full lines in Fig. 3, then the said lever engagesthe rear end of the felly to press the same irmly against the stop I,thus locking the felly in place. The holder I is also provided with sidelugs I5 to hold the felly in place and prevent sidewise movementthereof. The lower ends of the slides H are pivotallynconnected by linksJ with a IOO 2 trasse treadle K under the control of the operators footto raise or lower the said slides and con sequently the beds Eand I, soas to move the fellies supported on the beds in and out of contact withthe respective cutter heads C and Ci.

When the machine is in the position shown in Fig. 2, the beds E and Iare in a lowermost position, so that the fellies placed on the beds arewith their respective outer and inner faces, a suitable distance belowthe corresponding cutter heads C and C. When the operator presses thetreadle K, the slides I-I are forced to slide upward, thus moving thebeds E and I in the same direction to bring the fellies in contact withthe revoluble cutter heads for planing the fellies, as hereinafter morefully described.

In order to hold the fellies firmly against their holders E and I', Iprovide a friction roller L for the felly on the holder E', the saidfriction roller being journaled in the lower end of an arm L mounted toslide vertically in suitable bearings N' attached to the har N securedto the frame A, as plainly shown in Figs. l and 2. On the upper end ofthe arm L presses the free end of a spring O secured at its middle tothe bar N, the other free end of the spring engaging a second arm L2similar to the arm L and also mounted to slide in a bearing N2 attachedto the bar N. On the lower end of this second frame L2 is jour naled afriction roller I..3 adapted to press on the inner face of the telly atthe time the latter is supported in the other holder I.

In order to impart a starting feed to the bed E, the following device isprovided: In the `holder E is arranged a transversely-extending pin Padapted to be engaged by the upwardly-extendin g arm of a bell cranklever Q journaled in a bearing R attached to a bar R connecting the twoslides II with each other. The horizontal arm of the bell crank lever Qengages the lower slotted end S of an arm S engaged at its upper slottedend S2 by a bolt Na secured to the bar N. Now, when the slides H areraised by the operator pressing the treadle K, as previously described,then the bar R carrying the bell crank lever Q is moved in the samedirection, wherebya swinging motion is given to the horizontal arm ofthe bell crank lever Q by the fixed arm S so that the vertical arm ofthe bell crank lever Q presses on the pin IJ and thus imparts a swingingmotion to the bed Ein the direction of the arrow a at the time the outerface of the felly supported on the said bed moves in contact with thecutter head C. When it is desired to cut a chamfer on the inner face ofthe telly at the time the latter is supported in the hed I, then thestop I2 is removed and a pattern plate T is employed secured by bolts orpins T in the holder I', as plainly shown in Fig. 3. The under side ofthis plate, which is of segmental form is adapted to be engaged by afriction roller U journaled on top of the bar R moving with the slides Il as above mentioned. On the plate T is arranged an up# wardly-extendinghook T2 adapted to pass into one of the spoke apertures Din the felly D,so as to hold the latter in position. The hook T2 is arranged inalignment with a recess T3 formed on the under side of the plate T sothat when the friction roller U moves into the said recess, then theentire bed I moves vertically downward by its weight a short distance,the elongated bolt apertures in the bearings G permitting such movement.By this arrangement the inner face of the felly D at the spoke hole D ismoved away from the cutter head C', so that no chamfer is cut around thespoke hole.

The operation is as follows: The operator in front of the machine, thatis, to the left of the beds E and I, of Fig. 2, first places the bed Ein position as shown in dotted lines in Fig. 2, by pulling the said bedforward in the direction of the arrow o. When the bed is in thisposition,the operator places afellyon the holder E', the said fellyabutting with its rear end onto the stop EQand is held in place sidewiseby the lugs E3. Then the operator swings the bed E rearward in theinverse di rection ofthe arrow a until it assumes the position shown infull lines in Fig. 2, whereby the middle of the felly is below itscutter head C. When in this position, the upper arm of the bell cranklever Q rests against the pin IJ and when the operator now presses thetreadle K to cause the slides H to slide upward, moving the bed E in thesame direction with the felly D thereon, then a starting feed is givento the hed E by the bell crank lever Q acting on the pin P as abovedescribed. Thus, at the time the outer face of the telly D is movedagainst the revolving critter head C a slight feed is given to the bedand consequently the felly supported thereon, so that the cutter headnears the timber and makes a smooth starting cut, thus avoiding accidentby tearing part of the timber of which the lelly is made. The upwardsliding motion of the slides II is limited byastop I-I' striking one ofthe bearings for the slides, it being understood that the stop isarranged on the slides, as shown in Figs. l and 2. By this arrangement,the felly D is fed only a required distance to prevent the cutter headfrom cutting too deep into the timber. Now, the operator pulls on thebedE so as to swing the hed in the direction of the arrow a', whereby thecutter head C removes the surplus ma,- terial on the outer face ofone-half of the telly, thereby planing one-half of t-he length of thefell-y. The hed E is then in the position shown in dotted lines in Fig.2 at the time the cutter head C has cleared the rear endof the telly.The operator then reverses the telly D on the holder E', and the abovedescribed operation is repeated so that the other half ot' the outerface of the felly is planed. Vhen this has been accomplished, the fellyis placed on the holder I of the other bed I and the operator thenplaces his left hand on the le- ICO IIO

ver I3 andthe rightfhand on the forward end of the bed I to swing thelatter rearward into of the felly, about one-half ofthe lengt-hVthereof, after which the operator releases thek treadle K to permit theslidesH to move downward with the bed I to enable the operator toreverse the felly on the bed I. -When this has beenv done, the abovedescribed operation is repeated and the other half length of the innerface of the felly is planed. VWhenever the operator desires to releasethe felly in the holder l', he releases the lever I3, so that the springI4 forces the same back to its normal position, as'shown in full linesin Fig. 2.

It is understood that the segmental holders E and I are made to suit thediameter of the wheels for which the fellies are intended, and thebearings Gr are bolted or otherwise fastened to the slides I-I at adistance from the cutter heads C and C corresponding to one-half thediameter of the Wheel, and the bearings G' are fastened to the slidesI-I at a distance from the cutter heads corresponding to one-half of thediameter of the wheel less the width of the felly. d

When the plate T is used instead of the stop I2, as previouslymentioned, for chamfering the inner face 0f the felly then roundedknives are employed on the cutter head C', and the felly is engaged bythe hook T2, as above described, the said hook serving as a gage to makethe spoke hole and spoke seat in a-proper relation to each other, and italso serves as a clamp to assist the lever l3 and roller L to hold thefelly in place during the timethe cutter does its work.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1.
